IMPROVEMENT IN PUMPS.

To all whom it may concern..-

Be it known that I, THEoDoEE J. MoGow` AN, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvementin Pumps; and Ido hereby declare that the following is a full, clear, and exact description of the same, reference being had tothe accompanying drawings, making a part of thisspeciiication, in which- Figure 1 is a vertical central section of my invention, taken in the line a: fr, Fig. 2; Fig. 2, a horizontal section of the same, taken in the line y y, Fig. l.

Similar letters of reference indicate corret spending parts in the two figures.

This invention relates to an improvement in the ordinary reciprocating pump; and it consists inconstructing and arranging the working parts 'thereof-to wit, the bucket-valves and lower valveseat-in such a manner that they may al1,when necessary, be readily withdrawn fromthepump-cylinder at one operation orsimultaneously without disturbing or lmoving the pump-cylinder, thereby renderng the labor of repairing comparatively light and inexpensive.

To enable those skilled in the artto fully understand and construct myinvention, I will proceed to describe it.

A represents a pump cylinder, andv B a coupling at its lower end,whieh is used to connect a pipe to the cylinder, in order to extend it the proper depth in the well, rbc.

C is a portion of the pumprod which is attached to the bucket D, the latter being provided with a suitable packing, a, and having a valve, E, iitted in it, with a valve-guard, c, above the valve. An ordinary puppet or rising` and falling I,valve may be used.

F is a valveseat, which is screwed into the lower end of the bucket I), and is provided with a shoulder, d, which abuts against the bottom of the packing a, clamping it between the shoulder and the lower edge of the bucket, as shown in Fig. l.

G is the seat of the lower valve, `commonly termeda check-valve.77 Thisseatis screwed by a left-hand screw, c, into the coupling B.

The check-valve (designated by H) may be of the same kind or construction as the bucketvalve E. I is the guardfof this valve', which is screwed on therupp'er part of the seat G. The valve-guard I may be secured to the seat G by one or more small screws, e, to prevent -upper part, of such dimensions that it may fit or work into the internal screw, iff.

flhe operation of the pump, so far as the raising of water or fluid is conc-erned, is the same as the ordinary lifting-pump. The lifti ing of the working parts from the pump-cyh inder A is effected byirst disconnecting" the pump-rod C from the brake, crank, or other driving part at the top of the well. The valveseat F-is then lowered until it comes in contact with the screw cX at the upper part of the guard I of the check-valve I-I, Aand the seat F is then turned from left to right,which causes the screw c"- to work upinto the female or internal screw, D, of the seat F, and the pump-bucket D,with its valve E and seat F, will be connected with theV guard I and scat G of the check-valve H, and when the guard I and seat F are screwed together in close contact a further turning of the rod C and seat F will, in consequence of the scat G of the lower or check valve, H, being screwed into the coupling B by a lefthand screw, be unscrewed from the coupling, and all ol the said parts may consequently be simultaneously withdrawn. from the pump cylinder A. by

simply raising the rod C.- Thus it will be seen that the working parts,when repairs are necessary, may be removed or withdrawn from the cylinder'without removing or disturbing the latter, and thepa-rts maybe inserted in the pump-cylinder A and secured in proper position by simply reversing the manipulation just described for withdrawing them therefrom. A great deal of labor and expense is consequently saved by the invention.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent, isha Providing the pump-bucket D or any sultfrom the pump-cylinder A, and also adj usted able part connected therewith, and the lower therein, substantial] y as and for the purpose Valve-guard, 1,01' any part attached to it,with herein-specified.

screws or their equivalents arranged in such THEODRE MCG OWAN. a manner that al1 the Working parts of the Witnesses: pump may, by a simple manipulation, be con- W. CHEDSEY,
